A leaked photo shows trays of batteries intended for iPhone 5S production, claims Nowhereelse.fr. The authenticity of the photo is difficult to ascertain; while it does appear to have been shot in a factory, the batteries themselves are unmarked. At the same time, they are roughly the same size as the battery used in the iPhone 5.

Possibly supporting the photo is the number of reported parts leaks during the past several weeks. Such leaks tend to accelerate whenever a new iPhone or iPad is about to go into mass production. Rumors have indicated that one or more new iPhones are entering production in either June or July, with an aim towards shipping in September.
